Title: High efficiently operating air conditioner
Inventor: OCHI JIYOUJI
IPC: H02P4/00
Filed: 1981-07-18
Abstract: PURPOSE:To drive an induction motor of air conditioner with high efficiency at both the 50 cycle and the 60 cycle by a method wherein middle taps are led out from both windings of the main winding and an auxiliary winding, and are enabled to be connected to an electric power source of the 60 cycle rated voltage. CONSTITUTION:When the induction motor is to be operated in the 50 cycle region converting a change-over switch 7 into inverted condition from condition shown in the fugure, because a voltage is applied to the whole of the number of turns of the main winding 2 and the whole of the number of turns of the auxiliary winding 3, the highest point of operational efficiency transfers to the light- load side according to an increase of winding of the main winding 2, and is made to conform to operational condition at the 50 cycle. While when the air conditioner is made to be operated in the 60 cycle region, by making the change-over switch 7 to be changed over condition shown in the figure, because the main winding 2 and the auxiliary winding 3 are converted into condition that the number of turns between the middle taps 5, 6 and taps 2a, 3a at the ends are removed, the highest point of operational efficiency transfers to the heavy-load side, and the air conditioner is made to conform to heavy-load operating condition at the 60 cycle.

Title: Die bonding method
Inventor: YOSHIDA MASAHARU
IPC: H01L21/52
Filed: 1988-05-10
Abstract: PURPOSE:To conduct die bonding in high quality with high accuracy by heating a die by a pre-alignment stage and performing die bonding. CONSTITUTION:A pre-alignment stage 3 is heated at a temperature, where joining properties are improved, by a heater 4. A die 2 is positioned onto the stage 3, and preheated. The die 2 is aligned by a position regulating piece 1 driven by actuators 5, 6. Consequently, joining, through which voids are hardly formed and which has excellent wettability, is enabled by the preheating and alignment of the die 2. Accordingly, die bonding is executed in high quality with high accuracy.

A selecting signal S is successively supplied to scanning electrode groups L1-LN to which the initializing signal RS is supplied, and a pulse where a high frequency AC pulse is superposed on a DC pulse P3 which is symmetrical to the DC pulse P1 and has the opposite polarity, is applied to ferroelectric liquid crystal by the potential difference between the signal S and a desired signal supplied to control electrode groups R1-RX, and the average voltage level applied to the display element is set to zero at the time of supplying the initializing signal and the selecting signal. Thus, the rewrite time of one screen is shortened.

Title: Timepiece
Inventor: SEKIGUCHI KANETAKA
IPC: G04G9/06
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To achieve various display, for example, by shielding the information of a lower-layer liquid crystal display panel with the shutter function of an upper-layer liquid crystal display panel by laminating a plurality of liquid crystal display panels. SOLUTION: A first liquid crystal display panel consists of substrates 11 and 13 and electrodes 12 and 14 and absorption-type and reflection-type polarization plates 21 and 22 on each substrate indicate reflection and transmission characteristics when the application voltage to a liquid crystal layer 15 between both the substrates is small and large, respectively. The second liquid crystal display panel consists of substrates 16 and 18 and electrodes 17 and 19. When the voltage of a liquid crystal layer 20 that the reflection-type and transmission- type polarization plates 22 and 23 have between both the substrates is small and large, the second liquid crystal display panel indicates transmission and absorption characteristics, respectively.  In this case, a shutter display part 30 of the first liquid crystal display panel consists of electrode structure with a wider area than a display part 41 of the second liquid crystal display panel and shields the display part 41 when the liquid crystal layer 15 has a small voltage. Then, as a large voltage is applied gradually, the reflection characteristics change to transmission characteristics, thus gradually shifting to opening and finally full opening and hence enabling the entire surface of the display part 41 to be recognized.

Title: Print control method, its device, printer and print system including the printer
Inventor: SATO YASUSHI
IPC: B41J29/38
Filed: 1995-05-11
Abstract: PURPOSE: To automatically attain desired printing without the intervention of the operator by informing an external device of a print data form processed by the printer and receiving print data suitable for the form from the external device. CONSTITUTION: At application of power to the printer, a print controller 203 sends a data conversion mode message to a network 210. A computer 201 or 202 having already been energized recognizes a print data form convertible by the print controller 203 from the message, selects the conversion mode according to the content of the message automatically and surely provides an output of data being able to be printed by a printer 101. When a power supply is supplied to the computer 201 or 202 later while the printer has already been energized, the computer 201 or 202 sends an inquiry message. The print controller 203 sends a message in response to the inquiry message. Thus, the conversion mode of print data is in matching with each other.

Filed: 1988-05-10
Abstract: PURPOSE:To seek to improve element characteristics without bringing out lowering of reliability or increase of element area by providing a semiconductor substrate forming an element and a surface protective film consisting of an amorphous semiconductor film accumulated on the surface of this substrate. CONSTITUTION:Such an opening 14 that the surface of a p-type area 12 is exposed is formed on a part of an SiO2 film 13, and here an electrode 15 is formed, and above this electrode 15 is formed a surface protective film 16 consisting of an amorphous semiconductor film. Hereupon, when electric field is added from outside, the charge of an amount that negates the electric field from the outside is formed in the surface protective film 16 consisting of amorphous semiconductor film, and the potential at the surface protective film 16 decreases like a quadratic function and the effect of potential ceases to reach the surface of a substrate. In addition, since the surface protective film 16 has capacity to shut out potential, shift of various kinds of impurity ions attached onto an element is prevented, and generation of deterioration of element characteristics is softened. Hereby, it can improve element characteristics without bringing about lowering of reliability and increase of element areas.

Abstract: PURPOSE:To easily obtain an approximate value of mechanical strength, by putting force on that which has made and unknown material adhere to a material whose mechanical strength is known, and measuring its distortion, in a method for testing the mechanical strength of an unknown material. CONSTITUTION:A material 2 whose mechanical strength is known, and an unknown material 1 are made to adhere to each other, by which a sample is prepared. To this sample, a load is put on a force point 5 by making a supporting point 4. When the stress-distortion characteristics are measured, the material 1 generates a remarkable deformation when a value of stress has exceeded (a) by a difference of mechanical strength between the materials 1, 2. As a result, mechanical strength of the unknown material 1 can be grasped. As for a compound and a mixture, the number of data is a few since a mechanical quality is different depending on a component ratio, a manufacturing process, a condtion, etc., but it is possible to easily obtain an approximate value of mechanical strength as to them.
